Title: Odd Khovanov homology
Speaker: Jake Rasmussen
Speaker Info: Princeton
Brief Description:
Special Note:

Khovanov homology is an invariant which assigns to a link in S^3 a family of bigraded homology groups whose graded Euler characteristic is the Jones polynomial. In this talk, I'll describe a variant of Khovanov's construction (joint work with Peter Ozsvath and Zoltan Szabo), which replaces the symmetric algebra appearing in Khovanov's definition with an exterior algebra. The resulting homology groups agree with Khovanov's over Z/2, but differ over Q.
